What's this about 64KiB blocksize hanging the system? Hang awhile then recover, or hang forever need a reboot? Is this a RAID thing or are normal disks at risk? It isn't obvious why a 64KiB blocksize would cause a problem in this day of multi GiB memory. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "[EMAIL PROTECTED]"
